Better handling for OST eviction.  Fixes for clearing the page cache,
imp_invalid handling, and improved import_event interface. Also
includes the tests and fixes added from 2732; one of those tests does
not yet passed so it is excepted for now.

Skip closing files for the self_export, and add a test.

Add a test to replay since, and add an OBD_FAIL style macro to create
a race condition in a specific location called OBD_RACE.

Rename "test_foo" files to "f<testno>" so they are deleted at the end of
the sanity.sh run.

enqueue reply if the extent was changed and granted immediately.  This
avoids overwriting the policy data if it was updated in the completion callback
before the reply was processed.

*  Fixed obdecho persistent object size at 1 MByte.

*  Changed test_brw data verification tests to work on a fixed 4k block
   rather than on page size to allow different page sized servers and
   clients.

Adds support for client-side write cache accounting via OST write credits
(grants).  There is not yet a "correction" algorithm for grants if they
get out of sync between the client and OST (OST can handle clients who think
they have grant but do not).  Peter had previously suggested that grants
should decay over time (faster on the clients than on the OSTs) so idle
nodes do not consume space they aren't using.

Use /proc/fs/lustre/osc/OSC*/cur_grant_bytes (and existing cur_dirty_bytes)
to check client-side cache values.

Includes lustre-side changes for lfsck support (create files with
specific objids, create specific objids on OSTs).

Also includes some changes to the testing scripts (local.sh, lov.sh, acc-sm)
so that they include a "client nid '*'" client and can be used for sanityN.sh
testing.  This has been put into the main acceptance-small.sh loop so that
sanityN.sh will be run on both single and multi-OST setups.
